Applications<br />
Motor monitoring with PTC in the<br />
winding:<br />
• For long starting and braking<br />
operations<br />
• For high switching frequencies<br />
• For increased ambient temperatures<br />
• When the cooling medium flow<br />
is restricted<br />
• For AC drive operation<br />
Highlights<br />
• All products are PTB-ATEX<br />
certified<br />
• Wire breakage and short circuit<br />
in the sensor circuit are displayed<br />
• Versions with hard-gold-plated<br />
<strong>relay</strong>s which are electronics<br />
compatible<br />
• Favorably priced compact device<br />
(A1 + 11 jumpered)<br />
• Either screw or cage clamp terminal<br />
connection system<br />

<strong>3RN1</strong> <strong>thermistor</strong> <strong>motor</strong> <strong>protection</strong><br />
<strong>relay</strong>: Today, <strong>motor</strong> <strong>protection</strong> is so simple<br />
The power and lifetime of <strong>motor</strong>s is essentially limited by the winding temperature. Motor<br />
manufacturers integrate PTC sensors in the <strong>motor</strong> winding if more stringent requirements prevail – e. g.<br />
for high ambient temperatures or where cooling is restricted. The <strong>thermistor</strong> <strong>motor</strong> <strong>protection</strong> devices<br />
operate according to the closed-circuit principle, detect these limit temperatures and switch the output<br />
<strong>relay</strong> contacts.<br />
